Maintained the previous forecast of scattered showers for Guam,
today and tonight. Satellite indicated spotty showers east of the
Marianas around 18Z. Possible we may few more showers for the CNMI as
the trade-wind trough passes through, but kept showers isolated for
today. Scattered showers look more likely for Guam as the more
convective weather is seen to the south. Also the TUTT producing some
activity near Yap with higher moisture to the south.
